PROTECTIVE SHIELD FOR HOT-AIR REGISTERS.

Application filed August 9, 1927. Serial No. 211,829.

This invention rela es to new and u: improvements in protective shields for hotair registers.

It the principal object of my invention to provide for floor and wall hot-air registers a simple, economically constructed and attractive shield to protect the walls and furniture from smoke, dirt and other substances carried into the room by the air currents.

It is still another object of my invention to provide removable means within the shield to contain water to mo... n the heated air which passes through the r Other important and .ncidental objects will be brought out in the following specili cation and particularly set forth in the subjoined claims.

In the accompanying drawings illustrating my invention, Figure 1 is a perspective vlew of my protective shield secured to a wall above a hot-air register in the latter. Figure 2 is a vertical sectional view taken through Figure 1, showing a water pan within the shield. Figure 3 is a sectional View taken through the register on the line 33 of Figure 2. Figure 4 is a perspective view of the shield without a water pan. Figure 5 is a vertical sectional view taken through the shield shown in Figure 1-. Figure 6 is a view of the frame of the shield, with the water pan, shelf and top removed. Figure 7 is perspective view of my protective shield for a floor register. Figure 8 is a vertical sectional view taken through the shield shown in Figure 7. Figure 9 a sectional view taken through the floor shield on the line 9-9 of Figure 8. And Figure 10 is a front view of the floor shield.

Referring to the accompanying drawings for a detailed description of my invention, the numeral 1 in Figures 1 and 2 designates one of my hot-air deflecting shields adapted to be secured to a wall 2 above a hot-air register 3 therein. This shield comprises a back 4 and sides 5, 5 stamped and formed from a sheet of suitable metal. The back 4 formed with a rectangular recess 6 to admit hot air currents from the register. as shown by the arrows in Figure 2. Two notches 7, 7 are formed at the upper end of the recess, as shown in Figure 6 to receive screws 8 for securing the shield to the wall. The sides 5, ,5 of the shield are bent at their edges to form flange portions 9 that incline upwardly to vertical flange portions 10.

'the construction shown in Figure 2.

At their top edge portions the sides 5, 5 are turned down as at 11 in Figure 2. Below 11 I 5, 5 are bent inwardly, and then to an inverted U shape as shown in Figure 2, to term inwardl aro'ectin ear suoports 12 for a tray 13. This tray has an inclined bottom, and a tall front side 14 which is in tight contact with the flange portions 10 of the shield sides 5. At its top, the iront side 14 of the tray is bent to hook over the ears 12 that project inwardly from the sides of the shield, The tray is thus firmly supported within the shield to hold a water pan 15 which is made from a single sheet of metal, with -its rear end turned down along the top edge to form a foot 16. This footholds the pen in a horizontal position upon the inclined bottom of the tray 13.

The water pan 15 is thus in a position to present the water it contains to the incoming hot air to moisten it. The hot air thus moistened passes out of the shield between a flanged top 17 for the latter and the top of the front side 14 of the tray. A part of this airpasses out of the shield below the tray. In both instances, it is deflected by the shield away from the wall 2 to prevent the deposit of soot, dirt and other deleterious particles upon it.

In Figures 4, 5 and 6 I have shown the same shield that I have just described, except that it has no water pan and is so constructed that the inclined bottom of the tray 13 is itself the hot air deflector. To make it so, the tray is moved up to the position it occupies in Figure 5 to close the top opening through which the moistened air issued in The tray is held in this upper position by the tongues 12 which in this instance are formed at the extreme tops of the sides 5, 5 of the shield.

In Figures 7, 8, 9 and 10 Ihave shown one of my shields adapted for floor registers. In Figure 7 such a register 18 shown secured to a floor 19.

This shield comprises a metal blank formed with a back 20 and sides 21, 21. Instead of the sides 21 tapering back as in the wall shield, in the present case, they are rectangular, having flanged feet 22 for attachment to the floor 19, one on each side of the register grille 18.

Below their top frontcorner portions, the sides 21, 21 are bent inwardly, and then to meir top front corner portions, the sides inverted U shape an siown in Figure 9, to form inwardly projecting ear supports 23, for a tray 24. This tray, like the tray 13, has an inclined bot-tom, and a tall front side 25 which is in tight contact with flanges 26 formed on the shield sides 21. At its top, the front side 25 of the tray 2% is bent to hook over the ears 533 that project inwardly from the sine oi the shield. The tray 24- thus irmly supported within the shield to hold a water pan 2? made from a single sheet of metal, with its rear end turned down along its top edge to form a foot 28. This toot holds the pan 2? in a horizontal position upon the inclined bottom of the tray In this position the pan 2'? holds the water in the path of the hot air entering the shield through the floor grille 19, to moist-en it. The hot air tl is moistened passes out of the shield in the direction oi the top arrows in Figure 8, between a flanged top 2i tor tl shield and the top of the "front side oi the ,y. A part of this air passes out of the s! eld below the tray. It th s seen that the shield will deflect the hot air issuing troin the floor register 18, away from a wall 30 behind it.

The parts of my ti ll improved shields for wall and floor hot air registers. ii'iay ;be stamped from sheet metal and easily assembled to enable them to be constructed for at a reasonable price.

I do not wish to be limited to the details of construction and arrangement herein shown and described, and any changes or modifications may be made therein within the scope of the snbjoined claims.

Having described my invention, 1 claim:

1. A shield for hot-air registers, comprising a back, sides connected to the latter and formed below their top edges with inwardly projecting ears, a transverse upwardly inclined hot-air deflecting member having a front side which is bent to hoe-l; over said ears, and a cover on said back and sides above said deflecting member.

2. A shield for hot-air registers, compris moses? ing a back, sides connected to the latter and formed below their top edges with inwardly proje ting ears, a cover on said back and sides, a tray having an upwardly inclined bottom, whain saic shield, a front side for said tray that is bent at its top edge to hook over said ears, and a water pan within said tray.

3. A shield for hot-air registers, comprising a back, sides connected to the latter and termed below their top edges with inwardly projecting ears, a flanged cover an Jlied to said back and sides, a tray having a front side bent at its top edge to hook over said ears, said tray having an inclined bottom, and a water pan having an elongated rear foot to hold it in a horizontal position in said the purpose specified.

d. A shield for hot-air reg'sters, co1nprising a baclr and sides formed from a single sheet ot metal, a flanged cover applied to said back and sides, said sides below their top edges being bent inwartl and then outwardly and inwardly to form ear supports, a tray having an inclined bottom and front side which is bent at its top edge to hook over said ears, and a. water pan supported in a horizontal position within the tray to moisten the hot air that passes over it and out oi the opening between the cover and the top side of the tray.

i. shield for hot-air registers comprisa back, sides connected to the latter, a secured between said sides and having "l bottom, and a water pan having an elon ated rear foot to hold it in a horizontal position in said tray for the purpose specified.
